Extra Details:: Thrombopoietin (TPO) is a lineage specific growth factor, produced in the liver, kidney and skeletal muscle. It stimulates the proliferation and maturation of megakaryocytes, and promotes increased circulating levels of platelets in vivo. TPO signals through the c-mpl receptor and acts as an important regulator of circulating platelets. Human and murine TPO exhibits cross-species reactivity. Recombinant murine TPO is a fully biologically active 174 amino acid polypeptide (18.7kD), which contains the erythropoietin-like domain of the full length TPO protein. This comprises the receptor binding domain of the Mpl-ligand protein. Source: Recombinant protein corresponding to mouse TPO expressed in E. coli. Biological Activity: Determined by its ability to stimulate the proliferation of human MO7e cells. The expected ED50 is <1.0ng/ml, corresponding to a specific activity of >1x10e6units/mg. Endotoxin: <0.1ng/ug of protein (<1EU/ug) AA Sequence: SPVAPACDPR LLNKLLRDSH LLHSRLSQCP DVDPLSIPVL LPAVDFSLGE WKTQTEQSKA QDILGAVSLL LEGVMAARGQ LEPSCLSSLL GQLSGQVRLL LGALQGLLGT QLPLQGRTTA HKDPNALFLS LQQLLRGKVR FLLLVEGPTL CVRRTLPTTA VPSSTSQLLT LNKF Protein Content: Verified by UV Spectroscopy and/or SDS-PAGE gel.
